MATERIALS FOR ORGANIC ELECTROLUMINESCENT DEVICES

摘要

The invention relates to electroluminescent polymers, which contain at least one structural unit, which comprises at least one phosphorescent emitter unit, to methods for producing said polymers, to mixtures (also called blends), solutions, and formulations that contain said polymers, to the use of said polymers in electronic devices, in particular in organic electroluminescent devices, OLEDs (OLED = organic light-emitting diode), and to electronic devices containing said polymers. The polymers according to the invention show improved efficiency and a longer service life, in particular when used in OLEDs.
